errno TES PATEN ,JOSEPH E. BLAINE, OF OK PARK, ILLINOIS,- ASSIGNOR TO MIEI-ILE PRINTING PRESS & MANUFACTURING COMPANY, 10F CHICAGO, ILLINOIS, A. CORPORATION OF ILLI- FEEEERPILE-ADJUSTMENT MEANS.

To all whom t may concern Be it known that I, Josnrn R. BLAINE, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Feeder-Pile-Adjustment Means, of whichV the following is a specification. v j

This invention `relates to feeder pile adjustment means. i

In my Patent Number 1,388,161, granted August 23, 1921, there is disclosed a reload ing feeder in which the pile of sheet material is` elevated by suitable means in accordance withrequirements, the pile and its support-v ing table being adjustable bodily in a lateral direction for aliningthe `sheets with respect toregister mechanism `for facilitating the register of sheets preparatory to printing said sheetsl More specifically, the patented structure includes bolts or threaded members which are adjustable for moving the pile and its table laterally. yAccordingly, considerable time is required to shift the pile. Under actual operating conditions it is common to find the sheet material in the pile to be arranged rather irregularly inso far as the edges of the sheets being in proper alinement is concerned. An operator of a printing press will find that the sheets are being properly fed and registered for a given period, and a little later may find that proper register becomes questionable or im possible because the particular sheets then being fed from the pile are too far out of a proper feeding position. It is not desirable to stop the press and accordingly there is need for quick and accurate lateral adjustment of the pile.

Therefore, one object of the invention is to provide simple, reliable and efficient means for quickly and accurately adjusting a pile of sheet material to facilitate alinement and register of the sheets.

Another object is to provide feeder pile adjustment means adapted to meet various requirements for successful commercial operation.

These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheet of drawings, in which- Figure 1 is a fragmentary elevational view of a feeder pile mechanism embodying my invention;

o Figure 2 is a fragmentary top plan view of the same;

Figure 3 is a detail view taken in the plane of line 3-3 of Figure 2;

Figure 4t is a plan view of an operating lever forming part of my invention; and

Figure 5 is a side elevation of the same lever.

t will be noted that my invention is disclosed in connection with a reloading feeder having a plurality of pedestals 10, only one of which is shown, and chains 11, only one of which is shown, by means of which piles of paper 12 may be elevated for facilitating the feeding of material sheet by sheet, as for example, 1 in connection with printing presses. rI`he pile of sheet material in each case is supported upon a table 13 which in turnis supported upon a` plurality of I- beams 14 having brackets 15 secured thereto which cooperate with the chains 11 for elevating the sheet piles. The structure thus far described is disclosed in my said Patent No. 1,388,161, granted August 23, 1921.

This present invention is an improvement on that disclosed in said patent and has to do primarly with reliable and .eliicient means for quickly and accurately adjusting the pile of sheet material to facilitate alinement and register of the sheets. In this connection it will be noted that the upper flange of each of the I-beams 14 is provided with a row of holes 16 for the reception of one or the other of the oppositely extending pins 17 formed on an operating lever 18 having a handle portion 19. These pins 17 are offset with respect to the handle portion 19 of the lever and located in one corner of a laterally eX* tending head 2O formed at one end of the lever. When one of the pins 17 is placed in one of the openings 16, as shown in full lines in Figure 2 of the drawings, the front edge of the head 20 of the lever will be in engagement with, or at least be in operative association with the associated edge of the table 13. If it is desired to shift the table with its pile of sheet material to the left, as shown in Figure 2, such is quickly and accurately accomplished by moving the lever in a clockwise direction as viewed in said figure, whereupon its active or curved portion 21 of the head 20, dueto the offset of said head, causes the table 13 and its pile of sheet material tobe shifted laterally, as indicated by dotted lines in Figure 2. rEhe 14 at the opposite ends for shifting Vthe table and pile to the right, as vievvedV in Figure 2. The lever 18 is reversible so that it may be used" With ease in a plurality of positions With respect to the I-beams 14.

i, The offset portion 20 of the head may be made as long as desirable and the eccentriclty oi' the curved 'face 21 with respect to the pin 17 may be varied in different levers in accordance with requirements.

By means of this arrangement the pile of sheet material may be quickly and accurately adjusted in a manner suchA that the pile or'1 sheet material may be placed for proper alinement and register ot' the individual sheets regardless of the positions Y in which they lie in the pile one with respect to the other.

It is my intention to cover all modilications of the invention falling Within the spiritand scope of the following claims.

I claim:

1. In a feeder pile mechanism, the combination of a supporting member for a pile of sheet material, a member upon which said supporting member is adj ustably mounted and havingrmeans forming fulcruming points for a. lever, and a lever Which may be fulcrumed With respect to saidfulcruming points and cooperating With said irst member for giving said members a relative movement whereby the position of the pilel of sheet material may be adjusted.

2. In feeder pile mechanism, the combination ot a support :torapile ofsheet ma.- terial, a member upon'which said support is adjustably mounted and having. a plurality of openings, and Va lever having a pin which may be received by saidopeningsforV fulcruming 'the lever, said'lever having a portion eccentric With respectfto said pin and engageable vvith respectto said support for adjusting the position of the pile.

3. In feederpile mechanism, thecombination of a support for. a pile of sheet material,

a member upon Which said support is ad-V Vjustab-ly mounted and having aA plurality of openings, and a lever havinga portion engageable with saidsupport and having a pin eccentrically. located and received by one of said openings whereby the lever may be tulcrumed and actuated for .shifting the position of the pile.
